OIL-PUMP.

SPECIFICATION forming part of Letters Patent No. 779,689, dated January10, 1905.

Application filed May 27, 1904. Serial No. 210,020.

T (tZZ whom it may concern.-

Be it known that we. J OSEPH V. CLARK and HERBERT S. BLYNT, citizens ofthe United States, residing at Steubenville, in the county of Jeffersonand State of Ohio, have invented certain new and useful Improvements inOil- Pumps; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form apart of this specification.

Our invention relates to a new and useful improvement in asteam-actuated oil cup or pump especially designed and constructed forthe purpose of preheating the oil contained in the reservoir before itis introduced into the oil-cylinders and from there forced into thesupply-line and thence to any point on the engine to be lubricated.

In the accompanying drawings, in two sheets, forming a part of thisspecification, we have illustrated our invention by several views, inwhich Figure 1, Sheet 1, is a side View of our oilpump having part ofthe oil-reservoir broken away to illustrate the means employed inpreheating the oil and carrying steam to the cylinder. Fig. 2, Sheet 1,is a top plan view of our invention. Fig. 3, Sheet 2, is a frontelevation of our oil-pump. Fig. 4, Sheet 2,

is a similar view showing the steam and oil cylinder in section. Fig. 5,Sheet 2, is a sectional view of the steam-cylinder as attached to theupper part of the oil-reservoir, showing means of introducing steam tothe same.

Numerals of reference designate like parts throughout the several views,in which the numeral 1 represents the oil-reservoir, having two footportions 1 extending at right angles therewith, and 2 a removable lid.Entering the reservoir near the bottom is a steam-pipe 3, passing upthrough the middle of the reservoir on the inside and connecting withthe steam-cylinder 4.

5 is a port for the admission of steam to the cylinder 4.

6 is a steam-actuated piston-rod operating in the cylinder 4 and havingthe head 7. v

Sis a packing-nut attached to the lower end of the steam-cylinder.

9 is a cross-head having supporting ends 10 l0 and secured to thepiston-rod 6 by a pin 11. Between the cross-head 9 and the bridge 13 isa spring 12 of sufiicient strength to raise the plungers 14 after'theyhave been pressed down by the admission of steam to the cylinder 4. Theupper ends 15 of the plungers 14 are threaded for the purpose ofadjusting the nuts 16, thus lengthening or shortening the stroke of thepump.

Entering the feet 1 of the oil-reservoir are the oil-cylinders 17, eachhaving a check-valve 18 in the bottom thereof.

19 is a groove formed around each oil-cylinder and having a plurality ofports 20 therein to permit the passage of oil to flow through while theplungers are pressing in the cylinders 17.

21 is a packing-nut secured to the top of each cylinder.

Communicating with an opening 22 in the side of the reservoir-foot 1 isa discharge-pipe 23, having a check-valve 24 located therein. Thisdischarge-pipe, leading to the engine, passes up parallel with the sideof the reservoir to a churn-valve 25, which regulates the supply of oilto the engine and returns the superfluity of oil through a pipe 26 tothe reservoir.

WVhen steam is admitted to the cylinder 4, the piston-rod 6 carries thecross-head 9 down over the threaded portion 15 of the plungers 14 untilit reaches the nuts 16, when the plungers will be forced into theoil-cylinders 17 By the adjustment of these nuts 16 the stroke of thepump may be lengthened or shortened.

Our oil-pump is connected to any steam-line which has a direct passageof steam flowing to the valves of the engine. Also our feed-line willconnect with any point on the engine to be lubricated. hen the enginegets an admission of steam through the valves to push the piston aheador back, the steam-cylinder on the pump will get an admission on the topthrough the steam-line 3 into the port 5. This press the plungers 1&down into the oil-cylinders, thus forcing the oil contained therein outthrough the ports 20 and through the opening 22 into the feed-line ordischargepipe 23. The check-valve 24E prevents the oil standing in theperpendicular pipe 23 from escaping back into the oil-chambers.

hen the valves of the engine cut oil the steam-supplies, they also cutoff the steam-supply to the cylinder of the oil-pump. V hen they open toexhaust, the steam in the cylinder on the oil-pump will exhaust with thesteam on the engine, and on this action taking place the spring 12,seated between the crosshead and the bridge 13, will raise the plungersand draw in through the check-valves 18 a full supply of oil ready forthe next admission of steam to the cylinder a, which will press theplungers down again, seating the check-valves and forcing the oil intothe discharge'line, as previously stated.

One of the main features and advantages of our oil-pump is whereby weconnect with the steam-line to feed our cylinder. At the same time itserves as a heating device for the oilreservoir, thus preventing the oilfrom freezing or becoming too thick for use. This preheating featurewill afford us a means of using the thickest kind of lubricants orgreases, the

same being reduced to a liquid or workable.

state and readily introduced through the discharge-line to the engine.

VVhileour invention only calls for the introduction of steam to one endof the cylinder, it is obvious that the piston may be operated back andforth by the introduction of steam to both ends of said cylinder, thusdoing away with the necessity of a spring for facilitating the returnmovement of the piston-rod. It is also apparent that our pump can bemade triple action instead of double,

as shown in the drawings, by simply adding a third oil-cylinderbetweenthe two specified, thus supplying oil to a triple-expansionengine instead of compound expansion, as intended with the pump shown inthe drawings.

This will in no wise depart from our original idea and intention, butwill be merelycarrying out our invention to meet the necessary demandfor such a lubricator.

Having thus fully shown and described our invention, what we claim asnew, and desire to secure by Letters Patent, is
